We encourage your mat to be rolled neatly, image side IN, and stored in a safe place. This will ensure that the mat stays free from creasing and the image integrity is not compromised.

Do not use strong cleaning solvents, nor do we recommend you machine-wash your mat..Below is a recipe for an herbal based natural cleaning solution: 1 cup white vinegar 3 cups filtered water 1 tsp tea tree oil 10-15 drops of essential oil of your choicePlace all ingredients into a spray bottle and be sure to shake before each use.
